Objective The pathogenesis of T2DM has not been elucidated.This study aimed to explore the association of FXR gene polymorphisms with the risk of T2DM in Eastern China population. Methods We collected 467 cases in the Health Examination Center of our hospital from January 2011 to December 2012.Ligase detection reaction was performed to test the genotypes in 240 T2DM patients and 227 controls.Unconditioned logistic regression analysis was used to explore the association of FXR gene polymorphisms with the risk of T2DM in different genetic models, after adjusting for age, sex, smoking and drinking status. Results Compared with AA genotype, GG significantly increased the risk of T2DM (P=0.017), while GA+GG approached marginal significance in association with T2DM (P=0.049) in rs1030454.For rs10860598, GA reduced the incidence of T2DM (P=0.025) compared with AA genotype, while GA+GG had marginal significance with T2DM (P=0.049).For rs11110411, CT or CT+CC could reduce the risk of T2DM compared with TT with P value of 0.016 and 0.024 respectively.Compared with AA, GA or GA+GG in rs17030270 was negative with the risk of T2DM with P value of 0.018 and 0.032 respectively. Conclusion FXR gene polymorphisms are associated with the risk of T2DM in northern Chinese Han population and the variation of FXR gene may play a role in the pathogenesis of T2DM.

To investigate the distribution of virulence associated factors of 5 strains of Streptococcus suis type 2 from slaughtered pigs isolated in Fujian province , 7 virulence genes were detected through PCR amplification. They were the glutamate dehydrogenase gene(gdh), the capsular polysaccharides gene(cps), the extracellular factor gene(ef), the muramidate-released protein gene(mrp), the suilysin gene(sly), the fibronectin-binding protein gene(fbps) and the virulence-associated sequence or f2. Among these 5 strains isolated, the virulence genotypes of 4 strains S.suis type 2 and strain SS2PFJ07 was gdh+/cps2J+/mrp+/ef-/sly-/fbps+/orf2+ and the other one strain isolated from slaughtered pigs was gdh+/cps2J+/mrp+/ef+/sly+/fbps+ /orf2+ respectively. This results showed that there are at least 2 virulence genotypes in Streptococcus suis type 2 from slaughtered pigs isolated in Fujian province.

Objective To explore the relationship between collateral circulation and clinical manifestation after se-vere stenosis or occlusion of internal carotid artery. Methods According to the clinical manifestation, 78 cases of ICA ste-nosis or occlusion confirmed by digital subtraction angiography (DSA) were divided into two groups:asymptomatic group (n=31) and symptomatic group (n=47). Collateral circulation pathway in circle of Willis and the mean flow velocity of the middle cerebral arteries (MVMCA) were measured by Transcranial Doppler Ultrasonography (TCD). The correlation of the types of intracranial collateral circulation and clinical manifestation was analyzed. Results ① The collateral circulation opening rate of severe stenosis or occlusion of internal carotid artery in 78 cases of patients was 70.5%(55/78). The collat-eral patency rate (27/31, 87.1% of patients) was higher in asymptomatic group than in the symptomatic group (28/47, 59.6%of patients)(P<0.01).②Collateral patency of anterior communicating artery (ACoA)in asymptomatic group (24/31, 77.4%of patients) was higher than that in symptomatic group (20/47, 42.6%of patients) (P<0.01). Collateral patency of ophthalmic artery (OA) in symptomatic group (21/47, 44.7%of patients) was higher than that in asymptomatic group(6/31, 19.4%of patients)(P<0.05). The opening rate of ACoA was significantly higher than that of either the posterior commu-nicating artery (PCoA) or OA collateral circulation in asymptomatic group (P<0.05).③The mean flow velocity of the af- fected side middle cerebral arteries (MVMCA) in asymptomatic group (51.58±12.36cm/s) was significantly higher than that in symptomatic group (32.23±10.31cm/s) (P<0.01). Conclusion The clinical manifestation is closely related to arterial circle of Willis collateral circulation opening after severe stenosis or occlusion of internal carotid artery and collateral patency of anterior communicating artery is the major collateral supply vessel.

Objective To explore the effect of pharmacological preconditioning wtith low-dose FK506 reducing subsequent ischemia-reperfusion injury in rabbit knee joint and to explore the possible mechanism of that. Methods Twenty four animal model of allograft heterootopic knee joint were established and divided randonly into three groups: IR group ( Ischemia-reperfusion group), KK506 group ( FK506 preconditioning group) and ST group(Sham control group). Vessels were clamped for 1 hour, and then grafts received reper-fusion. Tissues(for example muscles tissues) of pro-ischemia and reperfusion after 12 hours were obtained, and they were observed by microscope and electron microscope and were at aiysised with reverse transcription-polymerase chain reaction( RT-PCR) , Western Blot, DNA ladder, flow cvtometer. Moreover, the contents of MDA , NO and SOD in these tissues were examined by spectrophotometer Results As a result, we observed disoranized tissues and swollen cells in IR groups but trenchant tissues and intact cells in FK506 groups by microscope, vaeuolated and tumid mitochondrion in IR groups but non-vacuolated and intact that in FK506 groups. With FK506 preconidtioning, the contents MDA and NO were distiactly reduced but significant raised in FK506 group. Compared with IR group, DNA ladder of FK506 group were weakly, and apoptotic raetes reduce from 20% to 10% and the expression of TNF, IL-1 , Fas and FasL mRNA obviously down-regulated. At the same time, expression of HSP70 significantly up-regulated on protein and mRNA levels with RT-PCR and Western blotting analysis in FK506 group. Conclusion Pharmacological preconditioning with low-dose FK506(0. 3mg/kg) can induce tolerance of ischemia-reperfusion injury in rabbit allograft knee joint. Over-expression of HSP70 may he key factor of that.
